| description | Metal halide perovskites comprise a promising class of semiconductors with broad applications ranging from optoelectronics and photovoltaics to photocatalysis. To extend these applications to on-chip devices, on-site growth of perovskite nanocrystals with high positional accuracy must be achieved. In this thesis, we demonstrate a method for growing sub-50 nm halide perovskite nanocrystals with sub-50 nm positional accuracy. We first explore how local forces can be engineered to control particle positioning at the nanoscale. We then show how our parameters of control - namely template geometry and solvent contact angle - can be utilized to position nanocrystals within lithographic templates. This thesis reveals a unique strategy that overcomes the limitations of conventional lithographic processes for high-resolution growth of halide perovskites. |
